HARRrNG'f TON, a citizen of tlie'United States ofAmerica, and resident of McMechen, county ofv AMarshall, and Stateo'West Virginia,- have invented certain new .and useful .Improvements inMotion-Picture Machines, of which 1o a motion picture'caineraormachine.- 1'- provide a machine embodying aniotion vpicthe following isa specification.. .Y

This invention relates lbroadly motion picture apparatus, and'morespecifically to.

vThe primary object of the invention' is to ture camera whereby the'camera is-'shifted vat' a portion of'the filmvadvancing mechanism;

back and forth betweentwo separated ,eX- are stationarily mounted,respectively, on

cession, substantially the same stereoscopic eect'jis seen as if theactual object photo-- graplfed were viewed in binocular vision.' i A.urtlier object is to provide'a machine'.- of,` the character mentioned.in which the camera and the film are actuatedto reciproc-ate betweensuitably separated exposure positions and remain at rest in each of saidpositions for a short interval of time during which exposure is made'.x' v f' i A still further object is to provide, in a machine of* thecharacter mentioned, automatic means for advancing the filma defi`niteldistance between exposures, or during the reciprocating movement ofthe camera;

With these' and "other important objectsA in view, the invention resides'in the features of construction, arrangement of'parts and' combinationsof elements' which will herein'v after be exemplified, reference beinghad the accompanying drawings, in'whichn' Figure 1 'is a-'sectionalelevation of the.l

upper and'lower portions, respectively, of

lwhich are disposed the usual reels 2 and 3 for carrying-a film 4. Saidreels-2 and 3 arefcarried respectively,`by spindles 5 and 4 6 whicharerotatably' mounted in bea-rings 7 and v8'. carried by brackets 9 and 10which the upper and undei sides of a carriage 1l.

Said carriage is'niounted Ato travel laterally supportsupon which thecarriage' rides and lation to said 'carriage and designed to maintainthe; latter seated upon said members 12 is a pairof'hori'zontallydisposed parallel :members 14 similar to-said members 12 and betweenwhich a guide-piece 15 similar to said piece 13 and' forming a. part ofsaid Acarriage is 4slidable` Said brackets 9 and f V10 are respectivelymounted -uponsaid guide-pieces-15 and 13, as shown.' Said carriagellf'also includes a pair of opposite vertically' disposed end -membersv11?",.wlilich'g,are rigidlyconnected adjacent to vtheir'upper and loweredges, respectively,

Said ratchet.

wheels are fixed` on the opposite cylinder spindles 16 sol that rotation4imparted to either of the former is communicated to' the cylinder. Asis obvious, rotation ,of the large gear 22 'in one direction impartsfor- '.ward rotation tol the cylinder 17 through one cfs-aid gears 21and the associated pawl and ratchet, while. the other pawl freely ridesArearward over the teeth of the ratchet with which it is associated.Reverse rotation of the gear 22 imparts like forward rot-ation to saidcylinder through .the lastrnentioned gear 21 and the therewith asso- Iciated pawl'and ratchet, while the first mentioned pawl rides freelyover the teeth ot thetherewith associated ratchet.

i Extending longitudinally through the. cylinder 17 and the spindles 16and freely movable with respect to `said parts is a rod-18 the fopposite ends of which protrude -outward from. the outer ends of`saidspindles 16. Coil springs 26 are disposed in encircling relationtothe projecting ends of said rod, said springs being interposed between`collars 27 carried by said rod and the adjacent a ends of said cylinderspindles, said springs tending to yieldingly hold said rod againstlongitudinal movement with respect to the c'arriageand the parts carriedby` the latter and serving a purpose which will hereinafter beexplained.

AOne end of'saidiodlS has pivot-ally connected thereto an end of apitman 28 which has its opposite end mounted upon a crank- -pin 29carried eccentrically by a disk 30 which is fixed upon a shaft 31journaled in a bearing 32 carried by a bracket 33 mounted upon asuitable part of the casing 1.

Said shaft 31 has fixed thereon a small beve-l. gear 34 in mesh with alargebevel gear 35 carried by a drive-shaft 36 which is journaledin abearing 37 carried by the casing 1 and which carries an operating crank38 located outside the casing.-

. From the foregoing description it will be understood that drivingpower applied to i the shaft 36 through the crank 38 effects rotation ofthe shaft 31 and disk 30 through I the bevelgears 34 and 35.4 Rotationof said diskaccomplishes, through the inte'imediacy of the pitman 28 andthe rod 18, reciproca.-

tion of the carriage 11 on itstrackway between the fullline and dottedline posit-ions shown in Fig." 1 for alternately presenting lengths ofthe film' 4 for exposure at said positions! Disposed at the rear of, andfixed to or otherwise associated with, the large bevel gear 22 so thatthe latter will rotate therewith is a plate or disk 39 which carries onits rear face meanswhereby the extent olf rotary movement thereof and,consequently,

of the bevel-gear 22 is limited. Themove 70 ment-limiting means hereinshown, which is merely illustrative of one of various devicesv j i whichmight be employed, includes an arcuate rocker 40 located at anappropriate distance from the axis of saidldisk 39. Dis- .7.5 posed at asuitable angle with respect to eachother and extend-ing outward from theoppo-V i site ends of said rocker 40. are straight arms 42 and 43'whichserve as stops, being adaptled to seat alternately upon a'horizontal 80 guide-bar 41 to positively limit the extent of the forwardand reverse rotary movements of the cyliiider-actuating means, such5movements being accurately'predetermined in extent'to produce anadvanceof the 4film 85 through a definite dista-nce which is the distancerequisite to present successive exposure areas in properly spacedrelation.

Also carried by the disk -39 below the plane of the' guide-bar 4 1 aretwo arms 44 and 45 relatively ydisposed at an angle corresponding tothat of said .arms 42 and 43,-. said angle being located in the extendedradial line of the angle between said'arms and 1,13, but reverselydisposed. At. one 9.5 limit of -movement of the disk '39 the. larm 42rests flat upon the upper face of 'the guide-bar 41 and the arm 45 restsflat against:`

the under face ofl saidy bar, said .arms being disposed in parallelalinement. The arms' 100 43 and 44 are likewise arranged in parallelalinement so that, at the oppositelimit of rotary movement .of saiddisk, theyv occupy positions respectively closely overlyingandunderlying Said'guide'bar'. ln the position 10 5 shown Fig. 4, whichisvalso the position shown infull lines in Fig. 1, a downturned lip orhook46, with which the outer end of` the arm 45 terminates, is engagedwith a lug -or stop member- 47 y which is stationarily 110 mounted upona suitable support', asa 'member 48 of the frame, at a point midway be-`tween tlie opposite exposure positions as .sumed by v the carriage andthe carriageborne parts of the mechanism.. Said stop 47 serves both as astop whereby a positive limit is fixed for movement: of the carriage.and as a means whereby said disk 39 is positively maintained againstrotary movement during the last half of the shifting movement ofthecarriage and during the first lialfof .the return shifting movement.

A lip or hook 119 similar to the hook 46 4is carried by the outer end ofthe arm 44, the

same being adapted to interlock with said stop 47 at the opposite limitvof movement of A the carriage. .Assuming that the parts of the mechanismoccupy-the positions shown in full lines in Fig. 1, forward rotati.on ofthecrank 38 `130- ted-line position shown in said ligure.

moving forward, the arm 45 will be main will, through the intermediate'mechanism described, draw the carriage toward the dottained horizontal,sliding between the guidebar 41rand the stop 47, until the carriage 11reaches themidway position,` at which arm 44 assuming closely underlyingrelation to the guide-bar 41 and the arm 42 assuming overlying relationto said bar. 1 During the remainder of the reciprocating movement .ofthe carriage, as also during the first half 'of thereturn-reciprocation, the disk 39 is Amaintained against rotarymovement,'sa`id` arm 44 lbeing held between said bar 41 and the stop"47. When the hook 49 engages the stop 47 movement. of the carriage inthat direct-ion ceases and the carriage remains stationary for a slightinterval as'and for a purpose which Will presently be explained.

At the instant that the hook 49 engages 'the stop47, preventing furtherleft to right movement of the carriage, the shutter lo-I cated .Withinthe lens-holder 5 0 of the camf era, which projects oiitward through aslot (i2-in the casing, is opened in-a suitable manner, as by theengagement of an actuating lever or trigger 51 with a stationary arm 52located at an'appropriate point upon the front Wall of the casing 1.

I The stoppage of the .carriage and tlie` simultaneous opening of theshutter, as ex-A plained, occursslightly prior to that-point in theoperation ot the carriage-actuating means Where the pitman 28 and therod 18A lie in direct alinement, so that the carriage,

A the film and the parts of the photographic mechanism proper remainstationary with the shutter open during an interval of time necessary toeffect a proper exposure. The coil spring .26 carried by theleft-handend of said rod 18 is. compressed and rexpands.

' during said interval, the saine being suiliciently contractile topermit the rod 18 to'V move through the cylinder 17 the requisitedistance to permit the pitman 28v` to .passovercenter,` or over thepoint at Which said pitman and said rod are in alined-relation'. As isobvious, the duration of the period or interval during which the parts'of the photographic apparatus remain stationary andfocused upon theobjective may I increased or diminished 'by substituting pitmen ofrelatively shorter or greater.

In the right to left movement, the carriage is stopped by engagementofthe hook 46 with the stop 47, and the shutter is opened by engagementof the trigger 51 with a second suitably located arm 53, slightly' prior'lemme Y 25, as shown..

rod 18 assuinealined relation, thecoil spring at the right-hand end ofsaid rod permit v ting the slight additionaljlonfritudinal travel ofthe'latter .necessary to. aloiv. the pitinan to pass over center-,orinto such alined relation. Thus, asis apparent, the photographicapparatus remains stationary' and the shutter remains open at each ofthe exposure'positions throughout the short period required to effect aproper exposure. y

" The extent of thevrotaryanovement iinparted to tliecylinder'lf? Withveach actuation thereogtf-in the'v manner -liereinbefor'e de` scribed issuch thatthe f ilm`4 is. advanced between successive exposures. vsuch adistance 'that anew exposure areaA ot' theI requisite length ispresented in*` line with the lens. 4 Said film travels through' avertical passage 54 provided therefor in a suitable lilm-guide v8 5 55which is-rigidly mounted upon the front side of the carriage 11. Said'film-guide has a rectangular 'openingl'or gate 56' in the front facethereof throu'g which the requisite areafo'f thel ilm is exposed, andhas a similaropeningf57 in its rear face which 'perf .mits thelpins 1,9-carried bythe cylinder 17 to unobstructedlyj.'engage,the ilin for ad.vancing'the'latter. y i

y The i-'eel'3 upon which the, film is being wound is rotated lby anysuitable means, as by. a belt 58 connecting pulleys 59 and 60' carried,-respectively,'by the spindle 6 and the outer faceof one o 'f theratchetWheels 10.0 -From theforeg'oing description it `Will be understood thatcontinuous .rotation of the. operating crank I38 produces reciprocationof the carriage 11 'and thev photographic ap-v paratus carriedv therebybetween'two estab- 105 lished exposure positions located a suitabledistance apart;'that said carriage and'apparatus remain-'at rest in eachof said positions throughout a suitable interval of time, and that theJrlight-excludingshutter f said apparatus' remains openduring suchlinterval,` permitting exposure of' a suitable length ofthe film.-Further, the film is advanced adelinite distance at a midway point ineach reciprocation lso thatA a new area thereof is presented at-eachexposure position.- 'Y A As will be yap arent, successi-ve picturescarried by t. the' :lm are' the result of exposures taken at' pointslocated at a definite -120 alternately from the tWo slightly separated vpoints of view being caused to`I blend or dissolve to producestereoscopic vision in which the observer receives the-impression of asingle image viewed with' both eyes. 130
